The present invenion relates to si valve to be nppiied -o radiators for the imi-pone of per- Viiing cold air to escape from them, in order to give pince to the Sienin; and the object et' the said invention is to provide n valve that wili not only permit the nir to escapo and pri Vent the escape of. Sienna, but that wiii also eieotnaily prevent the @soupe of wider.

The discharge of nir through the outlei rf wili then he resumed and wiil eoniinue until ng'nin interrupted by the presence of' either steam' or water in thel easing, :is described.

in order to prevent iiie'zvlir or Steaun as it enters the 'mire-Casing from blowing tho flonb liront its sont ind thais prematnreiy closing y end of the post E.

the outlet, the discharge end of 4tho'iul-ct. duct a is situated at one sideof the float, so that it cannot "discharge directly beneath the float. As a further precaution n shield is placed between theinlet and float. This shield preferably consists of a. jacket Il',wl1ch surrounds the dont, and is preferably -foruied athottoi'n with an oiiseth, that rests upon the base A, and al contracted portion 7i', that occupies the annular groove a? and surrounds the lower This jacket is ot' such-diameter that but little space is I cft betweeuit und theeasiug B, and-to provide for the llrec upward passage of the a-'ir or steam :t crimp or groove h2 is formed in its side opposite the inlet e. l'It is also provided at o r near its bottom, and preferably opposite the inlet a3, with an opening h3, through which wid-'or may escape. v

'ihe entrance to .the outlet c is situated. some distiiucc below'the ceiling di. the easir'ig,I

. so thatjtheair or steanr vthat strikes against the ceiling` will he compelled to pgiss inv a downward direction before it can enter said outlet, as? indicated bythe arrows, and as o eonsequenceany'water that it may carry with it will'be preei'pitutedand fall into' the jacket II, whence it may flow through opening h? into the duet u und back into the radiator.

In'orderto increase the superficie-l area of the post E it is made hollow, sind in order to admit haatte its' interior it .isprovided with. encor more lateral perforations e.

By'providing the inner end ofLscrew C with counterborc c', it nets ns n guidciorthe valve G and insures its proper seating.

Having thus described my invention, the following is what I claim ns new therein and desire to Secure by Letters Patent:
